Drag and drop Stackmon, resources and items onto each other to form powerful combinations! Use your Stackmon to gather materials, craft items, automate tasks and battle other Stackmon. Grow and customize your Harmony base to unlock new recipes, upgrades, and abilities for your Stackmon.
Discover and collect over 100 rare and powerful Stackmon and train and evolve them into their more powerful forms. Search for wild Stackmon across the world of Gaia, open booster packs to expand your collection, and help Professor Pine in his dream of completing the Stackpedia!
Venture beyond your base and challenge other Scouts scattered across the world to prove your strength and rise your way through the ranks. Take on rival Scouts in strategic auto-battles, using equipment, abilities and elemental affinities to your advantage. Face off against powerful Scout Leaders and show the strength of Harmony!
A mysterious and dangerous force is spreading throughout Gaia, corrupting any Stackmon and Scout Leaders in its path... It's up to you and your Stackmon to find the source of the corruption, face the Soot and change the fate that approaches.
